MongoDB vs RocksDB: What are the differences?
What is MongoDB? The database for giant ideas. MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
What is RocksDB? Embeddable persistent key-value store for fast storage, developed and maintained by Facebook Database Engineering Team. RocksDB is an embeddable persistent key-value store for fast storage. RocksDB can also be the foundation for a client-server database but our current focus is on embedded workloads. RocksDB builds on LevelDB to be scalable to run on servers with many CPU cores, to efficiently use fast storage, to support IO-bound, in-memory and write-once workloads, and to be flexible to allow for innovation.
MongoDB and RocksDB can be categorized as "Databases" tools.
"Document-oriented storage" is the top reason why over 788 developers like MongoDB, while over 2 developers mention "Very fast" as the leading cause for choosing RocksDB.
MongoDB and RocksDB are both open source tools. It seems that MongoDB with 16.3K GitHub stars and 4.1K forks on GitHub has more adoption than RocksDB with 14.3K GitHub stars and 3.12K GitHub forks.
Uber Technologies, Lyft, and Codecademy are some of the popular companies that use MongoDB, whereas RocksDB is used by Facebook, LinkedIn, and Skry, Inc..
